"That's not a gas tank, THIS is a gas tank!" ~ KTM Dundee
Damn, you could swim laps in that thing. It does seem like two-strokes just get sweeter and sweeter as you up the displacement. I remember the power of the 390 Husky (biggest bike I've ridden so far) being just absolutely intoxicating. It had low-end like a freight train and then it still built up to that typical two-stroke insanity up-top. In terms of getting a bike to have fun on, I definitely recommend getting something with a big Grizzly-Bear sort of piston living in it. 300 seems to be about as big as they go in mainstream these days, but I'm sure it's still got some significant balls.
